I talked George into detouring to Chimney Rock National Historic Site on our way to Scottsbluff, Nebraska. We saw the famous landmark about 10 minutes south of the turnoff. It gives you an idea of how visible it would have been to the pioneers. They'd been traveling two months since they left Independence, Missouri, and this was the most famous landmark on the Oregon, California and Mormon Trails.
